The fate in the Free World is threatened when three atomic scientists decide to sell their secrets to the Reds. American secret agent Steve (George Brent) heads to Tangier, where he poses as a black marketer in hopes of intercepting the rogue scientists. But Steve finds he has a formidable foe in the shapely shape of Soviet spy Millicent (Mari Aldon), who is posing as an American heiress to throw the Good Guy off the track. Dan Seymour, veteran of such espionage mellers of the 1940s as Casablanca and To Have and Have Not, has a juicy role as the head of the Tangier police. Tangier Incident wasn't quite an "A" picture, but it was too slick and expensive-looking to qualify for a "B."
